Hi All

This is my first post on here and I have spent most of the bank holida weekend reading through this whole thread.

I am about to purchase a new engine for my Hobao / Ofna Hyper ST, and reading through here has pretty much sold me on a Go engine. I use the truggy for bashing only, I might do some club races for fun sometime this year.

I was going to go for the 21 5 port as it seems to have the same power as the 25, but with better economy.

Now after readimg these posts, I am confused. Would I be better off going for the 25 6 port with a 2047 pipe, or a 21 5 port with the same pipe? Does anybody have actual dyno charts they can mail me of these mills standard please?

I wil be bashing with guys that have LRP Z.28 spec 3's and the like in their Hypers so don't want to be left too far behind when bashing. I don't really want to go for a 28 due to the run times.

Also, where is the best place to buy a 2047 pipe with hard coating in the US?

Cheers
